- ging, of which the following is a full, clear and exact specification.

- Myinvention concerns improvements in that type of draft mechanism of railway cars which transmits the pulling and bufling centerthe coupler.-

strains comparatively evenly to -all of. the longitudinal beams or sills of the car underframe instead of subjecting the center sills only to such strains. To eifect'this result,

the draft beam-or frame is-ri idly fastened to the bodybolster', whereby t e strains put upon the draft beam are transmitted to the body bolster and through-the latter a-re distributed to all the longitudinal;- beams: or-

sills,.and the form of my draft mechanism is: such. that it maybe attached to many standard ty es of bolsters without necessn tating any 0 ange in their construction.

--In the preferred form of my device, the

draft beam or frame is secured to the outerside or face of the bolster and by means of bolts or other securin vmeans is connected to a back plate or tai piece on the rear or inner side of thebolster, whereby a firm andsecure connection with the :bolster is obtainedt I Another object of my invehtion'is ,to provldea simple and efiecti've means for ern'-' ployingv the draft springs automatically On the accompanyin drawings which formra part of this speci cation, I have illustrated-a desirable embodiment of m invention and in all of the views of said rawings like referencecharacters refer to the same parts throughout.

the sides of the bolster is the usual kingpin bearing member 14; the apertureld of which is in alinementand registers with the holes 16 and 17 in plates 10 and 11, respectively.

Althou detail the construction of the bolster ortransom, the details of its construction are immateriah since my invention lies'in'the draft rigging described below and manner of attachment to the bolster.

The draft mechanism incl'udes; a draft beamor frame 18 which is of substantially r-rem in cross-section, as shown in Figs, :nomprising the upper horizontalplatje portion 19, the similar'lower horizontal plateed verticalconnecting. web 2-1;.

The inner or righthand endof the draft-frame or beam 18 as viewed in Figs 1 and 2, is provided with a plate or end portion 23'sha ed to: conform substantially to the side of tii center. On'the opposite or inner face of the bolster is placed "a back plate or tail piece casting 2 L similar inshape to the part 23 and designed to conform to the outline of the side'of the bolsterL In order to secure and rigidly fasten. the

the pmpuamoimt; flmkingpin' bearing 14 'ders 45 and 46 of the spring pocket, I

27 which, at their opposite ends, have on largements or seats 28 lying against the inner faces of the sides of the bolster. As an additional means to hold the parts togetherand prevent them from being wrenched out of place I employ a comparatively wide top or cover plate 29 which overlies the central portion of the bolster and the rear end of the draft frame or beam, being riveted to ;set upwardly at 35 and.- extends outwardly laterally to provide ears beneath the projections 33, If desired, the top and bottom 31 and 34 may be apertured, as at 36, to secure a minimum of weight, without a sacrifice of strength. To brace the lower portion of this spring pocket, the bottom part of its v'e'rtical'rear wall 37 is connected to the under side of plate 20 along its marginal edges by a pair of downwardly projecting tapering flanges 38 integral with the. draft member and with the spring pocket.

Housed within spring pocket 30 and adapted to reciprocate longitudinally therein is a yoke 39, the inner face of whose rear wall 40 is equipped with a pair of spring seats or housings 41, located on opposite sides of the longitudinal center of the yoke. At its front end yoke 39 has a pair of spaced forwardly projecting arms 41" adapted to straddle the shank 42 of a coupler 43. Extended transversely through an aperture in shank 42 is a bar 43 whose ends project into longitudinal slots 44 in the arms 41, these slots being longer than the width of bar 43, whereby the coupler is permitted to have a len hwise movement relative to the yoke; Within spring pocket 30, and normally abutting against the rear end of shank 42 and against the top and bottom vertical shoul rovide a plate follower 46 which has proiiecting inwardly from its face two spring centering pins or supports 47.

I sup ly the device with two pairs of in net and outer coil springs 48 and 49, respectiyely, which at one end are seated against the rear wall 40 of the yoke, and at their other end press against the inner face of the follower 46, being fpositioned on opposite sides of the center 0 the draft mecha nism whereby an automatic centering of the copiplei' is secured. The cars 33 of parts 32 35 are bolted together outside of the outwardly in pulling the car, the coupler shank 42 transmits its pull through bar 43 to the arms 41 of the yoke, the rear wall 40 of which compresses springs 48 and 49, the front ends of the springs being held from movement by the follower plate 46 which rests against the shoulders 45 and 46. When the coupler is forced inwardly, as in the act of coupling or backing the car, yoke 39 remains stationary, the ends of bar 43 traveling in slots 44. The inward movement of shank 42 forces follower 46 inwardly away from its co-acting shoulders and compresses the draft springs 48 and 49 so that the thrust upon the coupler is transmitted through the springs and the rear wall of the yoke directly to the draft frame. In both operations of pulling and bufling, the strains are transmitted to the bolster, and the latter,

in turn, distributes them to all of the longitudinal beams of the car underframe so that none of them are subjected to excessive or abnormal strains.

The draft springs being interposed between the follower and yoke as described and located on opposite sides of the center of the draft mechanism act to. center the 1.
